[Immunomodulation characteristics of Lactobacillus genus bacteria]
Summary
Live Lactobacillus bacteria enhance immune responses. This study shows their composition stimulates phagocytic activity, increasing natural killer cell cytotoxicity and cytokine production, including interferon and tumor necrosis factor.
Area of Science:
- Microbiology and Immunology
- Bacterial Therapeutics
Context:
- Investigating the immunomodulatory effects of specific Lactobacillus strains.
- Assessing the impact of a multi-strain Lactobacillus composition on cellular immunity.
Purpose:
- To evaluate the immunomodulatory properties of a defined Lactobacillus bacterial composition.
- To determine the effects of this composition on the phagocytic system, natural killer (NK) cell activity, and cytokine synthesis.
Summary:
- The study examined a composition containing live Lactobacillus delbrueckii subsp. bulgaricus LB86, L. delbrueckii subsp. delbrueckii DSM20074, L. rhamnosus LB3, L. acidophilus, and L. rhamnosus VR.
- Administration of this Lactobacillus composition led to a significant stimulation of the phagocytic system.
- This stimulation correlated with enhanced cytotoxic activity of natural killer (NK) cells and modulated the synthesis of key cytokines, namely interferon and tumor necrosis factor.
Impact:
- Demonstrates the potential of specific Lactobacillus strains as immunomodulators.
- Highlights the role of gut microbiota in regulating innate and adaptive immune responses.
- Provides a basis for developing probiotic interventions targeting immune system enhancement.

Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
Defense Against Bacterial Pathogens
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Probiotics
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Special Features of Adaptive Immunity
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Inducible Operons: lac Operon
The lac operon in Escherichia coli is a model for understanding inducible gene regulation and metabolic flexibility. It integrates local control by lactose and global regulation through catabolite repression, enabling E. coli to preferentially metabolize glucose when available and switch to lactose utilization when glucose is scarce.Structure and Function of the lac OperonThe lac operon contains three structural genes: lacZ (β-galactosidase), lacY (lactose permease), and lacA (thiogalactoside...
Microorganisms in Medicine and Therapeutics
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
